If you're a student of composition, orchestration or film-scoring or the like, this is a must-have. So many interesting things going on in there, and unless you have perfect ears - then you wouldn't need it anyway - the score is invalueable (?) if you want to see how Ravel obtained it. The score is in French, but with a glossary list on the front. However it's sometimes impractical to always flip the book, to see what the comments in the score mean. Very good binding and design, and shows why I like these slighty-larger-than-A4 Dover Publications.
